For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have eternal life. (John 3:16).
He who believes in the Son has eternal life; but he who does not obey the Son shall not see life, but the wrath of God abides on him. (John 3:36).
And this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day. (John 6:40).
I am the resurrection and the life; he who believes in Me shall live even if he dies, and everyone who lives and believes in Me shall never die. (John 11:25-26).
And to whom did He swear that they should not enter His rest, but to those who were disobedient? And so we see that they were not able to enter because of unbelief. (Hebrews 3:19).
Faith, if it has no works, is dead…You believe that God is one. You do well; the demons also believe, and shudder. (James 2:17,19).
